Load taken by Bolts Solution

Follow our step by step solution on how to calculate Load taken by Bolts?

FIRST Step Consider the formula

F Bolt = (\frac{π}{4}) \cdot ({d b}^{2} \cdot (n \cdot f t))

Next Step Substitute values of Variables

∴

F Bolt = (\frac{π}{4}) \cdot ({900mm}^{2} \cdot (3 \cdot 55N/mm²))

Next Step Substitute values of Constants

∴

F Bolt = (\frac{3.1416}{4}) \cdot ({900mm}^{2} \cdot (3 \cdot 55N/mm²))

Next Step Convert Units

∴

F Bolt = (\frac{3.1416}{4}) \cdot ({0.9m}^{2} \cdot (3 \cdot 55N/mm²))

Next Step Prepare to Evaluate

∴

F Bolt = (\frac{3.1416}{4}) \cdot ({0.9}^{2} \cdot (3 \cdot 55))

Next Step Evaluate

∴

F Bolt = 104.968464538069N

LAST Step Rounding Answer

∴

F Bolt = 104.9685N

How to Evaluate Load taken by Bolts?

Load taken by Bolts evaluator uses Load by Bolt = (pi/4)*(Bolt Diameter^(2)*(Number of Bolts*Allowable Stress in Stud Material)) to evaluate the Load by Bolt, The Load taken by Bolts formula is definedthe compression produced by the tightening of a nut against a bolt. The amount of weight that is placed on a bolt is, naturally, limited to how much it is capable of withstanding before coming apart. Load by Bolt is denoted by F_Bolt symbol.

How to evaluate Load taken by Bolts using this online evaluator? To use this online evaluator for Load taken by Bolts, enter Bolt Diameter (d_b), Number of Bolts (n) & Allowable Stress in Stud Material (f_t) and hit the calculate button.

FAQs on Load taken by Bolts
